Potent inhibitor of SRC-3 (steroid receptor coactivator-3)

 

Functions

Potent inhibitor of steroid receptor coactivator-3 (SRC-3). Blocks growth of MDA-MB-468 cells (IC50 = 3.4 nM) without effecting normal cells.1 It significantly inhibited breast cancer cell growth in an orthotopic MDA-MD-468 mouse model. Treatment of MCF-7 or triple negative MDA-MB-231 cells with SI-2 resulted in inhibition of proliferation and breast cancer stem cell (CSC) tumorsphere formation. CSC markers CD44⁺/CD24^-/1o and aldehyde dehydrogenase (ALDH) were also reduced indicating that SI-2 can selectively interfere with the TIC/CSC state in breast cancer cells.

 

Application Procedures

First dissolved in DMSO (up to 20 mg/ml), then diluted to aqueous buffer. Solutions in DMSO may be stored at -20° for up to 1 month.
